pd. phone is tecnically brand new, got it about 2 months with me, bought new
pd2. i've tried devoloper options to stop it, didnt work
pd3. i've done a hard reset and factory restore but didn't work
pd4. past days before the problem battery used to least around 9-11 hours with regular use, now i hardly get to 3-4 with regular use, intensive use before was around 4-5 hours, now not even 2 hours....
Please please help me!! i'm going mad with this problem....

yup, didn't work..

Did anyone find a solution to this problem? Same thing on my mate 20 pro. I also tried a factory reset without any luck

Maybe try to clear the cache from recovery would help.

HELP! Battery indicator automatically increasing without charging..

My lil' bro's GT2-P3110's battery indicator/notification became weird, it was started last night. The battery indicator/notification was increasing automatically without charging it. I've tried rebooting the device but it keeps on increasing. After rebooting, the battery indicator was 40% but after a few seconds it will increase until it reached 100%. It was frustrating because it didn't know what is the real battery status of the device. =(
I hope anyone can I help me out. Thanks in advance!
Are you on a stock rom ?

Thank you for your suggestion..I've already done factory-reset for the tab, but the problem is still there. Battery indicator still keeps on increasing. =(
standard thing to try whenever battery does weird stuff is use it till it shuts off, then WHILE TURNED OFF recharge completely and leave there for like 30 minutes after fully charging to make sure its "topped off" then see if the problem persists.
try hard reset or anther rom

Being unrooted has that one major advantage. Calling for support could lead to a manufacturer warranty replacement if they can't figure it out. Whatever you do/figure out, plz report back. Good luck!
My friend is having the same issue with his tab 2. He gave it to the service station. They simply flash the latest firmware and gave it back. The problem still remains the same. Even doing a factory hard reset hasn't solve the issue.

I've had the same issue in the past. I cant remember how I fixed it but I think you should get rid of the issue by deledit the battery atats from recovery, whiping dalvik and fixing permission. This of course would require a rooted tab. If you are not rooted the contact samsung.

This was happened to my phone too.
You're USB Port is damaged. You need the replace it.
same Issue occured today
i also faced the same issue today... tried to analyze it... here are my observations
1) the battery was fine cuz i played dead trigger,wild blood and dead space for 1 hr and then played 1080 p videos for 45 min to see if battery has given up..
that wasnt the case
2) Factory reset/ data in stock unrooted rom dosent help...
3)After the battery reaches 100% and if u restart the tab. it will start from 3 or 4 % and increase again... basically i think battery level goes above 100% ( yeah i know it sounds weird) and on restarting it will see 104% as 4%...
4) usb OTG was working fine so i can't find the fault the usb.. and the tab was registering charging ( the green line in battery stats) on plugging in the charger....
So i concluded that maybe there is something wrong with software rom/kernel in the system...
Anyhow I gave it to the service center... hope this gets solved soon :fingers-crossed:
Update : The motherboard had to be replaced... Seems the charging port damage cause fits in... So anyone facing this problem has high chances the charging port is damaged even if it might work fine

Help: Android system consuming 90% overnight... in deep sleep. Battery down by ~15%

I did a complete charge last night before I hit the sack. Battery was around 96%, today morning 80%!
I flashed stock ROM using TWRP, on first charge cycle battery is fine - just 1% overnight drain with 8 hrs SOT. On second charge cycle this issue hits me everytime.
All my radios are usually off (WiFi, NFC, Bluetooth, Data).
My phone seems to be in deep sleep a good portion of that time (See WLD statistics - attachment #1).
Android system sucks my battery during sleep and it was at 90% relative consumption when I woke up (See screen shot #1, Android sys has consumed 1840mAh!! This is ridiculously high for a phone that is apparently in Deep Sleep!)
Also attached screen shots from WLD for Summary, Kernal / Partial wakelocks & Alarms.
Device is rooted.
Going crazy trying to find out what's happening.
This happened with KangVIP and my current B180 ROM's which have great battery life as reported by other users here .
After you flased the ROM did you factory reset?

This is an unacceptable level of drain. I get similar numbers. This is getting very annoying. I am spending hours just debugging this nonsense.
When did you install / reset your ROM? What is the build you are on? I have read some posts that suggest to let the system be for first few days since it is in a "Learning Phase". Mine is currently in that phase.
Also, I find that many users here are not facing this issue on the ROM's that I am on, but some users are. I have faced this in multiple different ROM's.
Hence, I suspect this is an issue of some setting that we have changed. This is the first thing I do after reset / flash - modify a bunch of settings.
After searching and reading a lot, I have not come across any solid solutions from anywhere.
Here's a solution from the other thread. But I don't have this in system/apps. So this goes down the drain.

Couple others that are worth mentioning,
1. WiFi causing the drain (Am currently debugging this, modifying options).
2. Format SD card on new ROM, or just remove it (Would be great if you could try this out).
3. Factory reset has not solved for most people, but for some. (Did they *not* tweak some setting after reset?)
4. I think much of this drain is experienced after, charging and during sleep after that!

What value do u have for WiFi -> Advanced -> Keep WiFi on During sleep?
I had the battery drain till last night. Before sleeping I charged it completely, and modified this WiFi setting. Overnight I had only 2% drain as compared to +15% over last few days.
Battery looks good for now. I had the feeling that my WiFi is consuming more power than 4G (Need to verify if I am right). Currently observing.
I hope it is not one of those sporadic issues!

I presume u have been facing this issue at least over past few days now, not just a day or two.
Try toggling to Never. Recharge to full before you hit the sack. Lets see if that changes anything. This helped me, but need to observe for multiple consecutive days.

That's one of the first few things I disable. Nor do I use backup.
The battery drain is back. Disappeared for just a couple of days.
Is there anyone who knows how to fix this issue?
I would request you to do a back up of your apps and then factory reset and then again flash the ROM but via dload method.
Everything will be fine.
Then you can restore your apps

Huge battery drain all the time (hardware issue?)

Hey guys, I was hoping you could help me pinpoint the reasons why my Honor 8 suddenly can't get 2 hours of SOT and can't barely hold a charge for more than 6h with little usage.
Screenshots: https://imgur.com/a/AH8oFua
19% battery
49min with screen on

It's a FRD-AL10 model bought in Gearbest in August 2017 that came rebranded as FRD-L19C636.
It was working reasonably untill recently, when the battery began to die really fast, with no apparent reason.
When it first happened, it had B360 firmware installed.
I though that maybe forcing the update to B380 it would make a change. It didn't. Same for B390.
Did a Factory reset, no luck.
At that point I decided to unlock the bootloader and try custom roms, but the fact that the camera didn't work properly in none of them was enough to discard that option without further tests.
I went back to stock B360 (even though now the phone displays the test mode rom now - I'll handle it later).
So that's it: I've done several full formats and factory resets by now, and the battery performance remains poor, even though the phone is less than a year old.
This kind of happened suddenly, that's why I was thinking it was software related, but I'm not sure anymore, since the drain persists in multiple firmwares and after multiple resets, and cleanings of cache.
Thanks for the help!
It's cause of Google play services. They rolled out a bad update. The same is happening to my device. We'll have to just wait till they release a new update.

You need to roll back the update

Thank you guys, my girlfriend and I are both having battery drain issues. I really hope it is a software issue that will get fixed. We both really love the phone .
AccuBattery is consistently saying my battery health is around 1300mAh, after many recharge cycles.
This info persists after a brand new factory reset and rollback to B360.
I guess the battery is indeed the one main culprit here.

Android system+OS battery drain

Hey guys
At the beginning of my use of the OP the battery was really impressing, I also managed to reach the 7 Screen. The last week the battery has started to disappoint me, I thought at first that maybe the fault was that I was browsing too much on Facebook but i found out that Facebook is not at all causing the sharp drop in screen hours.
Android System and Android OS are my biggest waste of battery and come out in 3 1/2 hours of screen time. What can be done to improve it?
Man that's bad, i one played almost all day Kingdom Rush and world of tanks and my battery was still over 6h screen time. i don't know how that was possible

How it's your screen off/active graphs?
Are you phone rooted? If yes, you can install BetterBatteryStats to see what alarms/wakelocks are waking up the phone when inactive or find the app that are draining battery.

When I was using a Pocophone I knew Qualcomm-related bug that makes bluetooth prevents phone to enter deep sleep.
Try to disable bluetooth before restart and see the battery life. Maybe it helps
Hi!
I know that this will be a little bit clunky but i had the same problem (and lagg issues too) when i update from 9.5.8 to 9.5.9. The only solution was reboot on Recovery Mode (you can activate the advance power option from developer settings) and clear/wipe the caches and dalvik.
I dont know in with version of OS are you but with Oxgen Updater (https://play.google.com/store/apps/details?id=com.arjanvlek.oxygenupdater&hl=es) update to 9.5.10 and reset caches.
Hope can i help!

This is strange, I think battery is faulty.. or maybe there is app u r installing after reset the device that may cause this Everytime? Or you could send for warranty.
After reset the apps i installed
Netflix
Telegram
Insta
Reddit
Twitter
Hotstar
Nothing else
I see you have two SIM cards - try to remove them both or switch phone to airplane mode and see if it lags.
- is it rooted?
- is it default kernel?
- is it a beta version?
- is it global or EU?

Not a hardware issue.
You are running some application, that probably has a memory leak or an errant background process.
What did you install recently?
Nothing wrong with a reset every few days.

definitely not problem, but temporary solution is not a solutioon acc to m
I reboot my phone(s) every day...actually I am now able to turn mine off every night...so....same thing.
The result??? I rarely have any problems on any of the phones I have ever owned.
Android is NOT Windows Server which can be up 24/7 365 with few issues. But Windows Server is WAY more polished than Android as it has existed far longer in the enterprise environment. So for those of you who complain about issues...and never reboot...well...............
I just formated my Oneplus 7t pro. Restarted a few times after initial configuration.
Still there's lag when opening dialer, settings, and sometimes keyboard pops up a bit late.
